Abstract: In this paper effects of aggregate flakiness on the compressive strength of concrete cubes have been studied using experiments. Total 30 cubes have been cast using normal, 5% of 8 mm, 10 mm and 12 mm size of flaky aggregates and 10% of 12mm size of flaky aggregate. NDT of the cast cubes using rebound hammer and ultrasonic pulse velocity have been also carried out. All the cubes were tested for compressive strength. Based on these data, comparative studies have been carried out to quantify the effect of flakiness and salient conclusions are drawn.

ABHISHEK SHARMA AND K.K. PATHAK  National Institute of Technical Teachers’ Training and Research, Bhopal (M.P.), India Email: abhishek08887@gmail.com Abstract: Many project suffers time and cost overruns due to improper planning, scheduling and execution works that results in several issues like delay in providing facilities, development, reduction in quality of construction and making the project more expensive. A little consideration shows that the time required to complete the project is inversely proportional to the supply of manpower. As the manpower is increased, the completion time of the project is decreased and on the other hand if the manpower is decreased, the completion time of the project is increased. The present study deals with the manpower planning, scheduling and tracking of “Construction of a Residential Block at Mahadev Parisar, Bhopal”, a six storied (G+6) building project whose construction is in progress at Shivaji Nagar, Bhopal, Madhya Pradesh.

SHEENA ANGRA, SACHIN AHUJA  Ph.D Scholar, Chitkara University, India Associate Director, CURIN, Chitkara University, India E-mail: sheena.angra@chitkara.edu.in, sachin.ahuja@chitkara.edu.in Abstract: Data mining offers a new advance to data analysis using techniques based on machine learning, together with the conventional methods collectively known as educational data mining (EDM). Educational Data Mining has turned up as an interesting and useful research area for finding methods to improve quality of education and to identify various patterns in educational settings. It is useful in extracting information of students, teachers, courses, administrators from educational institutes such as schools/ colleges/universities and helps to suggest interesting learning experiences to various stakeholders. This paper focuses on the applications of data mining in the field of education and implementation of three widely used data mining techniques using Rapid Miner on the data collecte

Application of Silica Fume and Nanosilica in Cement and Concrete – A Review

Sakshi Gupta  Assistant Professor, Civil Engineering Department, Dronacharya College of Engineering, Gurgaon, Haryana, India Email: ersakshigupta18@gmail.com Abstract: This paper reviews the recent developments and present state of the application of silica fume (micro-silica) and nano-silica for sustainable development of concrete industry. This would save not only the natural resources and energy but also protect the environment with the reduction of waste material. Limited work is done on use of nano-silica and microsilica in paste, mortar and concrete and whatever work is available is highly contradictory about their influence on mechanical strength development and durability properties. Various literatures have been reviewed to understand the influence of micro and nano-silica on fresh, hardened and microstructural properties of paste, cement mortar and concrete. Taking advantage of nanostructure and microstructure characterization tools and materials, the simultaneous and
